Abstract
Description
本発明は、建築物などの仕切り部において形成される区画貫通処理構造、区画貫通処理構造を形成するための区画貫通処理材、及び区画貫通処理構造の施工方法に関する。 The present invention relates to a compartment penetration treatment structure formed in a partition of a building, a compartment penetration treatment material for forming the division penetration treatment structure, and a construction method for the division penetration treatment structure.
集合住宅、オフィスビル、学校等の建築物において、壁等の仕切り部には、ケーブル類、配管類などの長尺の挿通体を通すために、区画貫通部が設けられることがある。区画貫通部は、いずれかの区画で火災が発生した際に、他の区画への延焼を防止するために、防火措置を施した構造（耐火構造）にすることが求められている。仕切り部は、２枚の壁部からなり、壁部間が中空部となっている中空壁が一般的である。 2. Description of the Related Art In buildings such as housing complexes, office buildings, and schools, partitions such as walls are sometimes provided with compartment penetration parts for passing long objects such as cables and piping. Compartment penetrations are required to have a fireproof structure (fireproof structure) in order to prevent the spread of fire to other compartments in the event of a fire occurring in one of the compartments. The partition is generally made up of two walls, each having a hollow space between the walls.
区画貫通部を耐火構造とする方法は、例えば、長尺の挿通体と貫通孔の間隙に、耐火パテなどの不定形充填材を充填する方法が知られている。不定形充填材を使用する場合、各壁部の貫通孔内部と、挿通体の間には、耐火材よりなる筒状部材などが合わせて配設されることもある（例えば、特許文献１、２参照）。 As a method for making the compartment penetration part fireproof, for example, a method is known in which the gap between the elongated insertion body and the through hole is filled with an amorphous filler such as fireproof putty. When using an irregularly shaped filler, a cylindrical member made of a fireproof material may also be provided between the inside of the through hole of each wall portion and the insertion body (for example, Patent Document 1, (see 2).
しかしながら、区画貫通部の防火処理に不定形充填材を使用した場合、作業者によるバラつきがあり、十分な耐火性能が得られないことがある。また、躯体内に耐火材及びその付属品等を設置する場合、それらがどの程度（量や厚み、長さ等）設置されているか明確でなかったり、規定通りに設置されているか判断できなかったりすることがある。そのため、規定通りに耐火材などが設置されているか否かを確認するためには、区画貫通処理構造を破壊して、内部構造を確認する必要がある。 However, when an amorphous filler is used for fire protection treatment of a compartment penetration part, there are variations depending on the operator, and sufficient fire resistance performance may not be obtained. In addition, when installing fireproof materials and their accessories inside the building structure, it may not be clear to what extent (amount, thickness, length, etc.) they have been installed, or it may not be possible to judge whether they have been installed according to regulations. There are things to do. Therefore, in order to confirm whether fireproof materials etc. have been installed as specified, it is necessary to destroy the compartment penetration treatment structure and check the internal structure.
また、作業者によるバラつきを低減するため、あらかじめ決められた量、及び大きさの部材が一体化されたキットがあったが、部材点数が多い傾向があり、部材紛失や設置し忘れが生じやすく、また、キットごとの梱包のため、発生するゴミが多いという問題もある。 In addition, in order to reduce variations among workers, there were kits that included parts of predetermined quantities and sizes, but these tended to have a large number of parts, making it easy for parts to be lost or forgotten to be installed. There is also the problem that a lot of waste is generated because each kit is packaged.
また、内部にケーブル類及び配管類等の長尺の挿通体が挿通される区画貫通構造においては、区画貫通処理構造を施した後に挿通体を動かした場合には、内部に設置された耐火材などが設置されていた適切な位置からずれてしまうことがある。また、地震等の外力によっても、耐火材などが設置されていた適切な位置からずれてしまうことがある。また、耐火材が均一に膨張せずに偏って膨張すると設置されていた適切な位置からずれたり、脱落したりすることがある。このように、耐火材などが設置されていた適切な位置からずれてしまうことによって、区画貫通部の耐火構造として望まれる耐火性能を発揮することが困難となる。 In addition, in compartment penetrating structures in which long cables, piping, etc. are inserted, if the penetrating bodies are moved after the compartment penetration processing structure has been applied, the refractory material installed inside etc. may be displaced from their proper position. Additionally, external forces such as earthquakes may cause fireproofing materials to shift from their proper positions. Furthermore, if the refractory material does not expand uniformly and expands unevenly, it may shift from the appropriate installed position or fall off. In this way, when the refractory material and the like are displaced from the appropriate position where they were installed, it becomes difficult to exhibit the desired fireproof performance as the fireproof structure of the compartment penetration portion.
そこで、本発明は、耐火性能のバラつきを低減し、かつ耐火性能を向上させることができる区画貫通処理構造、区画貫通処理構造の施工方法、及び区画貫通処理材を提供することを課題とする。 Therefore, an object of the present invention is to provide a compartment penetration treatment structure, a construction method for the division penetration treatment structure, and a compartment penetration treatment material that can reduce variations in fire resistance performance and improve fire resistance performance.

以下、本発明について実施形態を用いてより詳細に説明する。 Hereinafter, the present invention will be described in more detail using embodiments.
［第１の実施形態］
本発明の第１の実施形態に係る区画貫通処理構造は、図１に示すように、建築物の仕切り部１１に形成され、かつ内部に長尺の挿通体２１が挿通される区画貫通部１５を耐火構造とする区画貫通処理構造である。
[First embodiment]
As shown in FIG. 1, the compartment penetration processing structure according to the first embodiment of the present invention is a compartment penetration part 15 that is formed in a partition part 11 of a building and into which a long insertion body 21 is inserted. It is a compartment penetration treatment structure with a fireproof structure.
本発明の区画貫通処理構造における仕切り部１１は、建築物の壁面において区画間（第１の区画Ａと、第２の区画Ｂ）を仕切る部材であり、仕切り部１１の一方の外面１１Ａ側から他方の外面１１Ｂ側に貫通する区画貫通部１５を有する。図１で示す仕切り部１１は、中空壁であり、間隔（中空部１３）を介して配置される２枚の壁材（仕切り材）１２Ａ，１２Ｂから構成される。そのため、区画貫通部１５は、一方の壁材１２Ａに形成された貫通孔１３Ａと、他方の壁材１２Ｂに形成された貫通孔１３Ｂと、これらの間にある中空部１３によって構成される。そして、一方の壁材１２Ａの外面が仕切り部１１の外面１１Ａを構成し、他方の壁材１２Ｂの外面が仕切り部１１の外面１１Ｂを構成する。貫通孔１３Ａ，１３Ｂは、例えば、円形、楕円形、又は、これらに近似する形状を有すればよい。なお、外面１１Ａ、１１Ｂそれぞれにおいて貫通孔１３Ａ，１３Ｂは、仕切り部１１に設けられた区画貫通部１５の開口１３Ｃ，１３Ｄを構成する。 The partition part 11 in the partition penetration treatment structure of the present invention is a member that partitions between the partitions (first partition A and second partition B) on the wall surface of the building, and from the one outer surface 11A side of the partition part 11. It has a compartment penetration part 15 that penetrates to the other outer surface 11B side. The partition portion 11 shown in FIG. 1 is a hollow wall, and is composed of two wall materials (partition materials) 12A and 12B arranged with a gap (hollow portion 13) in between. Therefore, the partition penetrating portion 15 is constituted by a through hole 13A formed in one wall material 12A, a through hole 13B formed in the other wall material 12B, and a hollow portion 13 located between these. The outer surface of one wall material 12A constitutes the outer surface 11A of the partition section 11, and the outer surface of the other wall material 12B constitutes the outer surface 11B of the partition section 11. The through holes 13A and 13B may have, for example, a circular shape, an elliptical shape, or a shape similar to these. Note that the through holes 13A and 13B on the outer surfaces 11A and 11B constitute openings 13C and 13D of the partition through portion 15 provided in the partition portion 11, respectively.
なお、本明細書において、区画貫通部１５に施工され、区画貫通処理構造１０を形成するための部材（本実施形態では、テープ状部材４、及びこれらを固定するための固定部材など）を纏めて区画貫通処理材ということがある。
また、以下では、仕切り部１１の一方の開口１３Ｃ側における区画貫通処理構造の構成について説明するが、本実施形態では、他方の開口１３Ｄ側における区画貫通処理構造の構成も同様であるのでその説明は省略する。
In addition, in this specification, the members (in this embodiment, the tape-shaped member 4, the fixing member for fixing these, etc.) which are constructed in the compartment penetration part 15 and form the compartment penetration treatment structure 10 are summarized. It is sometimes referred to as compartment penetration treatment material.
Further, in the following, the configuration of the compartment penetration treatment structure on the one opening 13C side of the partition portion 11 will be explained, but in this embodiment, the configuration of the division penetration treatment structure on the other opening 13D side is also the same, so the explanation will be given. is omitted.
第１の実施形態に係る区画貫通処理構造１０は、区画貫通処理材として、テープ状部材４を備え、テープ状部材４が少なくとも、後述するとおりに耐火材層を有する。 The compartment penetration treatment structure 10 according to the first embodiment includes a tape-shaped member 4 as a compartment penetration treatment material, and the tape-shaped member 4 has at least a fireproof material layer as described below.
〔テープ状部材〕
テープ状部材４は、図１及び図２に示すように、挿通体２１の外周に一周以上巻き付けて配置し、仕切り部１１に設けられる区画貫通部１５の開口１３Ｃ及び仕切り部１１の外面１１Ｂと挿通体２１との間の間隙１３Ｅを塞ぐように設置される。テープ状部材４は、図２に示すように、挿通体２１の外周に一周以上巻き付けられた状態となることで、テープ状部材４には端面４Ａが形成され、端面４Ａによって、開口１３Ｃ及び仕切り部１１の外面１１Ｂと挿通体２１との間の間隙１３Ｅを塞ぐことが可能となる。ここで、本実施形態において、テープ状部材４は、区画貫通部１５の開口１３Ｃ及び仕切り部１１の外面１１Ｂと挿通体２１との間の間隙１３Ｅを塞ぐ位置に配置される限り、テープ状部材４と開口１３Ｃの間に別の部材があってもよい。テープ状部材４は、間隙１３Ｅの一部を塞ぎ、別の部材により間隙１３Ｅの残りを塞いでもよい。
[Tape-shaped member]
As shown in FIGS. 1 and 2, the tape-like member 4 is arranged so as to be wrapped around the outer periphery of the insertion body 21 for one turn or more, and is connected to the opening 13C of the compartment penetration part 15 provided in the partition part 11 and the outer surface 11B of the partition part 11. It is installed so as to close the gap 13E with the insertion body 21. As shown in FIG. 2, the tape-like member 4 is wound around the outer circumference of the insertion body 21 for one turn or more, so that an end face 4A is formed in the tape-like member 4, and the end face 4A forms an opening 13C and a partition. It becomes possible to close the gap 13E between the outer surface 11B of the portion 11 and the insertion body 21. Here, in this embodiment, as long as the tape-like member 4 is placed in a position that closes the opening 13C of the compartment penetration part 15 and the gap 13E between the outer surface 11B of the partition part 11 and the insertion body 21, the tape-like member 4 There may be another member between 4 and the opening 13C. The tape-like member 4 may close part of the gap 13E, and another member may close the remainder of the gap 13E.
テープ状部材４は、耐火性を有するパテ材により形成される耐火材層（パテ材）及び熱膨張性を有する膨張材により形成される耐火材層（膨張材）の少なくともいずれかを有する。テープ状部材４は、耐火材層を少なくとも有する構成であることで、区画貫通処理構造１０の防火性能を確保できる。 The tape-shaped member 4 has at least one of a fireproof material layer (putty material) formed of a fire-resistant putty material and a fireproof material layer (expansion material) formed of a thermally expandable expansion material. The tape-shaped member 4 is configured to have at least a fireproof material layer, so that the fire prevention performance of the compartment penetration treatment structure 10 can be ensured.
テープ状部材４に使用される耐火材層は、耐火性を有するパテ材により形成することができる。パテ材により形成された耐火材層は、火災等により焼失することがなく、耐火材層を維持することができる。パテ材は、後述するようにパテ組成物により形成されることが好ましい。
また、テープ状部材４に使用される耐火材層は、熱膨張性を有する膨張材により形成することができる。膨張材により形成された耐火材層は、火災等により耐火材層が膨張することで、設置されていた箇所に有する隙間等を埋めることができ、延焼を防ぐ等の耐火性を発揮することができる。膨張材は、後述するように熱膨張性樹脂組成物により形成されることが好ましい。
The fireproof material layer used in the tape-like member 4 can be formed from a putty material having fireproof properties. The fireproof material layer formed of putty material is not destroyed by fire or the like, and can be maintained. The putty material is preferably formed from a putty composition as described below.
Further, the fireproof material layer used in the tape-shaped member 4 can be formed of an expansion material having thermal expansion properties. The fireproofing material layer formed from an expandable material can fill gaps, etc. in the place where it was installed by expanding due to a fire, etc., and can exhibit fireproofing properties such as preventing the spread of fire. can. The expansion material is preferably formed from a thermally expandable resin composition as described below.
耐火材層の厚みは、特に限定されないが、例えば０．０１～１ｍｍ、好ましくは０．１～５ｍｍである。耐火材層がこれら上限値以下の厚みを有することで、テープ状部材４に柔軟性が付与される。また、下限値以上の厚みを有することで、耐火性能を確保しやすくなる。 The thickness of the refractory material layer is not particularly limited, but is, for example, 0.01 to 1 mm, preferably 0.1 to 5 mm. When the refractory material layer has a thickness that is equal to or less than these upper limit values, flexibility is imparted to the tape-shaped member 4. Moreover, by having a thickness equal to or greater than the lower limit value, it becomes easier to ensure fire resistance performance.
テープ状部材４に使用される基材は、耐火材層を支持し、耐火材層に熱を均等に伝達させる。基材としては、例えば、アルミニウム箔、銅箔等の金属箔、ガラスクロス、アルミガラスクロスなどの金属箔とガラスクロスの複合体等の金属箔複合体、紙、布、樹脂フィルムなどが挙げられる。これらのなかでは、耐火性の観点から、不燃材料で構成されることが好ましく、具体的には、金属箔及び金属箔複合体が挙げられる。不燃材料とは、建築基準法及び建築基準法施行令において定められるものである。
基材は、挿通体２１とは反対側の位置にある最外層に配置されていることが好ましい。テープ状部材４の最外層に基材が配置されていることで、内側に配置されている耐火材層を良好に支持し、耐火材層に熱を均等に伝達させることができるため、耐火材層の機能を発揮しやすくさせることができる。また、テープ状部材４の意匠性を高めることができる。
The base material used for the tape-like member 4 supports the refractory material layer and evenly transfers heat to the refractory material layer. Examples of the base material include metal foils such as aluminum foil and copper foil, glass cloth, metal foil composites such as composites of metal foil and glass cloth such as aluminum glass cloth, paper, cloth, and resin films. . Among these, from the viewpoint of fire resistance, it is preferable to be made of a noncombustible material, and specific examples thereof include metal foil and metal foil composite. Noncombustible materials are those specified in the Building Standards Act and the Building Standards Act Enforcement Order.
The base material is preferably disposed in the outermost layer at a position opposite to the insertion body 21. By disposing the base material on the outermost layer of the tape-shaped member 4, it can support the refractory material layer disposed inside well and evenly transmit heat to the refractory material layer. It is possible to make it easier for the layers to perform their functions. Moreover, the design of the tape-shaped member 4 can be improved.
基材の厚みは、特に限定されないが、例えば０．０１～２ｍｍ、好ましくは０．０５～１ｍｍである。不燃材料層がこれら上限値以下の厚みを有することで、テープ状部材４に柔軟性が付与される。また、下限値以上の厚みを有することで、耐火性能を確保しやすくなる。 The thickness of the base material is not particularly limited, but is, for example, 0.01 to 2 mm, preferably 0.05 to 1 mm. When the noncombustible material layer has a thickness that is equal to or less than these upper limit values, flexibility is imparted to the tape-shaped member 4. Moreover, by having a thickness equal to or greater than the lower limit value, it becomes easier to ensure fire resistance performance.
テープ状部材４は、基材及び耐火材層が少なくとも３層積層されている。テープ状部材４が基材及び耐火材層が少なくとも３層積層されている構成であることで、耐火性能のバラつきを低減し、かつ耐火性能を向上させることができる。
テープ状部材４は、図３（ａ）～（ｅ）に示すように、基材及び耐火材層が交互に少なくとも３層積層されている構成とすることが好ましい。具体的には、テープ状部材４は、図３（ａ）に示すように、基材４ａ１，４ａ２及び耐火材層４ｂ１が交互に３層積層されている構成とするとよい。例えば、基材／耐火材層（パテ材）／基材、又は、基材／耐火材層（膨張材）／基材とすることができる。なお、耐火材層（パテ材）とは、パテ材により形成される耐火材層を意味する。耐火材層（膨張材）も同様に、膨張材により形成される耐火材層を意味する。
The tape-like member 4 has at least three laminated layers of a base material and a fireproof material layer. Since the tape-shaped member 4 has a structure in which the base material and the fireproof material layer are laminated in at least three layers, variations in fireproof performance can be reduced and the fireproof performance can be improved.
The tape-like member 4 preferably has a structure in which at least three base materials and fireproof material layers are alternately laminated, as shown in FIGS. 3(a) to 3(e). Specifically, the tape-like member 4 may have a structure in which three base materials 4a 1 , 4a 2 and a refractory material layer 4b 1 are alternately laminated, as shown in FIG. 3(a). For example, it can be base material/fireproof material layer (putty material)/base material or base material/fireproof material layer (expandable material)/base material. Note that the refractory material layer (putty material) means a refractory material layer formed of putty material. A refractory material layer (expandable material) also means a refractory material layer formed of an intumescent material.
テープ状部材４は、図３（ｂ）に示すように、基材４ａ１及び耐火材層４ｂ１，４ｂ２が交互に３層積層されている構成とするとよい。例えば、耐火材層（パテ材）／基材／耐火材層（パテ材）、耐火材層（パテ材）／基材／耐火材層（膨張材）、耐火材層（膨張材）／基材／耐火材層（パテ材）、又は、耐火材層（膨張材）／基材／耐火材層（膨張材）とすることができる。なお、以上の記載においては、左側が挿通体２１から最も近い内周側であり、右側が挿通体２１から最も遠い外周側である。以下も同様である。これら構造のうち、少なくともパテ材により形成される耐火材層を有することが好ましい。
例えば、テープ状部材４が、パテ材により形成される耐火材層と、膨張材により形成される耐火材層とを備えることで、火災が生じたときにパテ材により形成される耐火材層によりテープ状部材４の形状を維持する一方で、膨張材により形成される耐火材層により火災の延焼を防止できる。また基材を挟み込むように、２つのパテ材により形成される耐火材層が設けられることで、火災が生じたときにパテ材により形成される耐火材層がテープ状部材４の形状を強固に維持し、それにより、火災が生じたときにテープ状部材４が崩落することを防止し、高い耐火性能を維持できる。
The tape-like member 4 may have a structure in which a base material 4a 1 and three refractory material layers 4b 1 and 4b 2 are alternately laminated, as shown in FIG. 3(b). For example, fireproof material layer (putty material) / base material / fireproof material layer (putty material), fireproof material layer (putty material) / base material / fireproof material layer (expandable material), fireproof material layer (expandable material) / base material / refractory material layer (putty material) or refractory material layer (expandable material) / base material / refractory material layer (expandable material). In the above description, the left side is the inner peripheral side closest to the insertion body 21, and the right side is the outer peripheral side farthest from the insertion body 21. The same applies below. Among these structures, it is preferable to have at least a refractory layer formed of putty material.
For example, the tape-shaped member 4 may include a fireproof material layer made of putty material and a fireproof material layer made of an expandable material, so that when a fire occurs, the fireproof material layer made of putty material While maintaining the shape of the tape-like member 4, the spread of fire can be prevented by the fireproof material layer formed of the expandable material. In addition, by providing a fireproof material layer formed of two putty materials so as to sandwich the base material, the fireproof material layer formed of the putty materials will strengthen the shape of the tape-shaped member 4 in the event of a fire. This prevents the tape-like member 4 from collapsing in the event of a fire, and maintains high fire resistance.
テープ状部材４は、３層構成に限られず、図３（ｃ）に示すように、基材４ａ１，４ａ２及び耐火材層４ｂ１，４ｂ２が交互に４層積層されていてもよい。例えば、基材／耐火材層（パテ材）／基材／耐火材層（パテ材）、基材／耐火材層（パテ材）／基材／耐火材層（膨張材）、基材／耐火材層（膨張材）／基材／耐火材層（パテ材）、又は、基材／耐火材層（膨張材）／基材／耐火材層（膨張材）とすることができる。 The tape-like member 4 is not limited to a three-layer configuration, and may have four layers of base materials 4a 1 , 4a 2 and fireproof material layers 4b 1 , 4b 2 alternately stacked as shown in FIG. 3(c). . For example, base material/fireproof material layer (putty material)/base material/fireproof material layer (putty material), base material/fireproof material layer (putty material)/base material/fireproof material layer (expandable material), base material/fireproof material The structure may be material layer (expandable material)/base material/fireproof material layer (putty material), or base material/fireproof material layer (expandable material)/base material/fireproof material layer (expandable material).
また、テープ状部材４において、基材／耐火材層のように１層ずつ交互に設けられる必要はなく、基材／基材、耐火材層／耐火材層のように同種の層が連続して積層してもよい。基材と耐火材層は、例えば、図３（ｄ）に示すように、基材４ａ１，４ａ２が連続して積層し、基材４ａ２，４ａ３及び耐火材層４ｂ１が交互に積層されていてもよい。

In addition, in the tape-shaped member 4, it is not necessary to provide one layer at a time alternately as in the case of base material/refractory material layer, but it is not necessary to provide layers of the same type in succession such as base material/substrate and refractory material layer/refractory material layer. It may also be laminated. For example, as shown in FIG. 3(d), the base material and the refractory material layer are such that the base materials 4a 1 and 4a 2 are continuously laminated, and the base materials 4a 2 and 4a 3 and the refractory material layer 4b 1 are laminated alternately.

本発明では、基材及び耐火材層が交互に少なくとも３層積層されていることで、テープ状部材４が加熱された場合に、耐火材層が基材に適切に支持されて熱を均等に行き渡らせることができ、耐火性を良好にすることができる。
また、テープ状部材４を使用することで、耐火パテ、ロックウールなどの充填材を区画貫通部１５の内部に配置することなく、耐火構造が形成されるので、作業者によるバラつきが生じることもない。

It can be spread evenly throughout the area, and the fire resistance can be improved.
In addition, by using the tape-like member 4, a fireproof structure is formed without placing filler such as fireproof putty or rock wool inside the compartment penetration part 15, so variations depending on the operator may occur. do not have.

For example, the layer structure of the base material and the refractory material layer may be partially changed.

Good too.
With the above configuration, the tape-like member 4 can be fixed to the insertion body 21 without using a fixing member separate from the tape-like member 4. Further, by imparting adhesiveness to the fireproof material layer itself, it is not necessary to provide an adhesive layer, so that the configuration of the tape-shaped member 4 can be further simplified. In addition, when the tape-like member 4 is provided with an adhesive fireproof material layer or an adhesive layer on its outermost surface, a release sheet may be attached to its outermost surface.

（熱膨張性樹脂組成物）
以下、耐火材層などの耐火材に使用される熱膨張性樹脂組成物についてより詳細に説明する。熱膨張性樹脂組成物は、樹脂成分と、熱膨張性材料を含有する。熱膨張性部材が、樹脂成分を含有する熱膨張性樹脂組成物により形成されることで、テープ状部材４の湾曲や変形が容易となる。
熱膨張性材料としては、加熱することにより発泡する発泡剤、バーミキュライト、熱膨張性黒鉛などの熱膨張性層状無機物が挙げられ、中でも熱膨張性黒鉛が好ましい。熱膨張性黒鉛を使用することで、火災の加熱により適切に膨張され、また、膨張後の膨張残渣の機械強度が優れ、耐火性を良好にしやすくなる。なお、ここでいう熱膨張性材料とは、後述する成形などによって実質的に膨張せず、熱膨張性樹脂組成物は、耐火材において熱膨張性が維持される。
(Thermally expandable resin composition)
Hereinafter, the thermally expandable resin composition used for a fireproof material such as a fireproof material layer will be explained in more detail. The thermally expandable resin composition contains a resin component and a thermally expandable material. Since the thermally expandable member is formed from a thermally expandable resin composition containing a resin component, the tape-like member 4 can be easily bent and deformed.
Examples of the thermally expandable material include foaming agents that foam when heated, thermally expandable layered inorganic materials such as vermiculite, and thermally expandable graphite. Among them, thermally expandable graphite is preferred. By using thermally expandable graphite, it is appropriately expanded by heating in a fire, and the expanded residue after expansion has excellent mechanical strength, making it easy to improve fire resistance. Note that the thermally expandable material referred to herein does not substantially expand during molding or the like described below, and the thermally expandable resin composition maintains its thermal expandability in the fireproof material.
熱膨張性材料の膨張開始温度は、特に限定されないが、例えば、１５０～３５０℃であることが好ましく、１７０～３００℃であることがより好ましく、１８０～２８０℃であることが更に好ましい。これら下限値以下とすることで、火災以外の加熱により、熱膨張性材料が誤って膨張することを防止する。また、上限値以下とすることで、火災の加熱により確実に熱膨張性材料を膨張させやすくなる。
また、熱膨張性材料の膨張開始温度は、所定量（例えば、１００ｍｇ）の熱膨張性材料を一定の昇温速度（例えば、１０℃／分）で昇温させ、法線方向の力が立ち上がる温度を計測することにより測定可能である。測定装置としては測定温度制御が可能であり、かつ法線方向の応力を測定できるものであればよく、例えばレオメーターを使用すればよい。
熱膨張性部材の膨張倍率は３倍以上であることが好ましく、１０倍以上が好ましい。膨張倍率の上限は、特に限定されないが、例えば７０倍、好ましくは５０倍である。カバー部材に膨張倍率が異なる複数の耐火材層が積層されている場合、膨張倍率は上記範囲内で選択するとよい。また、例えば、仕切り部の外面から最も離れた耐火材層の膨張倍率と、仕切り部の外面から最も近接した耐火材層の膨張倍率との差は、１０～８０倍であることが好ましく、２０～７０倍であることがより好ましく、３０～６０倍であることがさらに好ましい。
なお、膨張倍率は、熱膨張性部材を電気炉に供給し、６００℃で３０分間加熱した後、試験片の厚さを測定し、（加熱後の試験片の厚さ）／（加熱前の試験片の厚さ）により算出するとよい。
The expansion start temperature of the thermally expandable material is not particularly limited, but is preferably, for example, 150 to 350°C, more preferably 170 to 300°C, and even more preferably 180 to 280°C. By setting it below these lower limits, the thermally expandable material is prevented from erroneously expanding due to heating other than fire. Further, by setting the value to be below the upper limit value, it becomes easier to reliably expand the thermally expandable material by heating due to fire.
In addition, the expansion start temperature of the thermally expandable material is determined by raising the temperature of a predetermined amount (for example, 100 mg) of the thermally expandable material at a constant temperature increase rate (for example, 10°C/min), and the force in the normal direction increases. It can be measured by measuring temperature. The measuring device may be any device that can control the measurement temperature and measure the stress in the normal direction; for example, a rheometer may be used.
The expansion ratio of the thermally expandable member is preferably 3 times or more, and preferably 10 times or more. The upper limit of the expansion magnification is not particularly limited, but is, for example, 70 times, preferably 50 times. When a plurality of refractory material layers having different expansion ratios are laminated on the cover member, the expansion ratio may be selected within the above range. Further, for example, the difference between the expansion ratio of the refractory material layer furthest from the outer surface of the partition and the expansion ratio of the refractory material layer closest to the outer surface of the partition is preferably 10 to 80 times, and 20 It is more preferably 70 times, and even more preferably 30 to 60 times.
The expansion ratio is determined by feeding the thermally expandable member into an electric furnace, heating it at 600°C for 30 minutes, measuring the thickness of the test piece, and calculating the following formula: (Thickness of the test piece after heating)/(Thickness of the test piece before heating) It is best to calculate it based on the thickness of the test piece).

熱膨張性黒鉛の粒度は、特に限定されないが、２０～２００メッシュの範囲のものが好ましい。粒度は、下限値以上となると黒鉛の膨張度が大きくなりやすく、発泡性が良好になる。また、上限値以下とすることで、樹脂と混練する際の分散性が良好となり、成形性が向上する。 The particle size of the thermally expandable graphite is not particularly limited, but is preferably in the range of 20 to 200 mesh. When the particle size is equal to or greater than the lower limit, the degree of expansion of graphite tends to increase, resulting in good foamability. Further, by setting the amount to be below the upper limit, the dispersibility when kneading with the resin becomes good, and the moldability improves.
熱膨張性樹脂組成物における熱膨張性黒鉛の含有量は、樹脂成分１００質量部に対して、例えば３質量部以上３００質量部以下である。熱膨張性黒鉛の含有量は、３質量部以上となることで、熱膨張性が良好となる。また、３００質量部以下となることで、成形性が良好となり、シール部材の表面性、機械的物性、柔軟性なども良好となる。また、熱膨張性黒鉛の含有量を上記範囲内で選択することで、膨張倍率を所望の範囲内に調整しやすくなる。これら観点から、熱膨張性黒鉛の含有量は、好ましくは１０質量部以上２００質量部以下の範囲であり、より好ましくは１５質量部以上１００質量部以下の範囲である。 The content of thermally expandable graphite in the thermally expandable resin composition is, for example, 3 parts by mass or more and 300 parts by mass or less based on 100 parts by mass of the resin component. When the content of thermally expandable graphite is 3 parts by mass or more, thermal expandability becomes good. Furthermore, when the amount is 300 parts by mass or less, moldability becomes good, and the surface properties, mechanical properties, flexibility, etc. of the sealing member also become good. Furthermore, by selecting the content of thermally expandable graphite within the above range, it becomes easier to adjust the expansion ratio within a desired range. From these viewpoints, the content of thermally expandable graphite is preferably in the range of 10 parts by mass or more and 200 parts by mass or less, more preferably in the range of 15 parts by mass or more and 100 parts by mass or less.

According to the configuration of this embodiment described above, the gap 13E inside the opening 13C of the partition penetrating portion 15 is closed by the tape-shaped member 4, and at least the tape-shaped member 4 has a fireproof material layer. Therefore, appropriate fire resistance can be imparted to the compartment penetration treatment structure 10, and its construction is easy.

［第２の実施形態］
次に、本発明の第２の実施形態について詳細に説明する。第２の実施形態において、第１の実施形態と相違する点は、図６に示すように、テープ状部材４を覆うカバー部材５を備える構成である。以下、第２の実施形態について、第１の実施形態との相違点を説明する。また、説明を省略する部分は、第１の実施形態と同様である。また、以下の説明では、上記第１の実施形態と同一の構成を有する部材には同一の符号を付す。
[Second embodiment]
Next, a second embodiment of the present invention will be described in detail. The second embodiment differs from the first embodiment in that it includes a cover member 5 that covers the tape-like member 4, as shown in FIG. Hereinafter, differences between the second embodiment and the first embodiment will be explained. Further, parts whose description is omitted are the same as those in the first embodiment. Furthermore, in the following description, members having the same configuration as those in the first embodiment are given the same reference numerals.
カバー部材５は、基材を少なくとも有する。カバー部材５は、単層からなるものでもよい。カバー部材５は、基材及び耐火材層が少なくとも２層積層されていることが好ましい。
カバー部材５は、内側に覆って配置されている部材を良好に保護することができる。つまり、カバー部材５でテープ状部材４を覆う構成とすることで、内側に配置されているテープ状部材４を良好に保護することができるため、テープ状部材４の機能を発揮しやすくすることができる。
カバー部材５は、少なくとも２層積層されている場合は、挿通体２１とは反対側の位置にある最外層が基材であることが好ましい。カバー部材５の挿通体２１とは反対側の位置にある最外層が基材であることで、意匠性を高めることができる。
The cover member 5 has at least a base material. The cover member 5 may be made of a single layer. It is preferable that the cover member 5 has at least two laminated layers including a base material and a fireproof material layer.
The cover member 5 can satisfactorily protect the members disposed to cover the inside. In other words, by configuring the cover member 5 to cover the tape-like member 4, the tape-like member 4 disposed inside can be well protected, so that the function of the tape-like member 4 can be easily exhibited. I can do it.
When the cover member 5 is laminated with at least two layers, it is preferable that the outermost layer located on the opposite side from the insertion body 21 is a base material. Since the outermost layer of the cover member 5 on the opposite side to the insertion body 21 is a base material, the design can be improved.
カバー部材５は、シート状であり、かつ、変形できることで、挿通体２１に容易に密着させて配置することが可能であり、テープ状部材４を容易に覆うことが可能である。
カバー部材５は、図６に示すように、例えば、四角形であり、かつ挿通体２１が内部に挿通されるためのスリット５４を有し、スリット５４の少なくとも１つがカバー部材５の外縁まで延在する。スリット５４は、切込みにより形成される。カバー部材５は、外縁まで延在するスリット５４を介して、挿通体２１をカバー部材５の内部に挿入させることが可能である。本実施形態では、挿通体２１をスリット５４により内部に挿入させたカバー部材５は、適宜変形されることで、一部を仕切り部１１上に配置させ、かつ挿通体２１に巻き付けるように設置させることができる。
Since the cover member 5 is sheet-like and deformable, it can be easily placed in close contact with the insertion body 21, and can easily cover the tape-like member 4.
As shown in FIG. 6, the cover member 5 is, for example, square and has a slit 54 through which the insertion body 21 is inserted, and at least one of the slits 54 extends to the outer edge of the cover member 5. do. The slit 54 is formed by a cut. The cover member 5 allows the insertion body 21 to be inserted into the cover member 5 through a slit 54 extending to the outer edge. In this embodiment, the cover member 5 into which the insertion body 21 is inserted through the slit 54 is appropriately deformed so that a part thereof is placed on the partition portion 11 and is installed so as to be wrapped around the insertion body 21. be able to.
カバー部材５は、粘着性を有する基材を挿通体２１から最も近い一面５Ａに配置する構成、又は、粘着剤層を備える基材を挿通体２１から最も近い一面５Ａに配置する構成とし、粘着性を有する基材又は粘着剤層によって挿通体２１に接してカバー部材５を配置するとよい。
また、カバー部材５は、粘着性を有する耐火材層を挿通体２１から最も近い一面５Ａに配置する構成する構成、又は、粘着剤層を備える耐火材層を挿通体２１から最も近い一面５Ａに配置する構成とし、粘着性を有する耐火材層又は粘着剤層によって挿通体２１に接して配置されてもよい。
粘着剤層は、粘着剤により形成されるとよく、粘着剤としては、例えば、アクリル系粘着剤、ウレタン系粘着剤、ゴム系粘着剤、シリコーン樹脂系粘着剤等を用いることができる。粘着剤層は、不燃性、準不燃性、又は難燃性であってもよく、使用する粘着剤に難燃剤などを配合してもよい。粘着剤層の厚みは、例えば５～４００μｍ、好ましくは１０～１５０μｍである。
以上の構成により、カバー部材５とは別部材としての固定部材を使用しなくても、カバー部材５を挿通体２１に固定させることができる。また、耐火材層自体に粘着性を持たせることで、粘着剤層を設けなくてもよいので、カバー部材５の構成をより簡素化できる。なお、カバー部材５は、その一面５Ａに粘着性を有する耐火材層、又は粘着剤層が設けられる場合、その一面５Ａに剥離シートが貼付されてもよい。剥離シートは、使用時に一面５Ａから剥離されるとよい。
The cover member 5 has a configuration in which an adhesive base material is disposed on one side 5A closest to the insertion body 21, or a configuration in which a base material with an adhesive layer is disposed on one side 5A closest to the insertion body 21, and an adhesive It is preferable that the cover member 5 is placed in contact with the insertion body 21 using a base material or an adhesive layer having adhesive properties.
The cover member 5 may have a structure in which a refractory material layer having adhesive properties is disposed on one surface 5A closest to the insertion body 21, or a fireproof material layer including an adhesive layer is disposed on one surface 5A closest to the insertion body 21. It may be arranged in contact with the insertion body 21 through a refractory material layer or an adhesive layer having adhesive properties.
The adhesive layer is preferably formed of an adhesive, and examples of the adhesive include acrylic adhesives, urethane adhesives, rubber adhesives, silicone resin adhesives, and the like. The adhesive layer may be nonflammable, semi-nonflammable, or flame retardant, and a flame retardant or the like may be added to the adhesive used. The thickness of the adhesive layer is, for example, 5 to 400 μm, preferably 10 to 150 μm.
With the above configuration, the cover member 5 can be fixed to the insertion body 21 without using a fixing member separate from the cover member 5. Further, by providing adhesiveness to the fireproof material layer itself, it is not necessary to provide an adhesive layer, so that the structure of the cover member 5 can be further simplified. In addition, when the cover member 5 is provided with an adhesive fireproof material layer or an adhesive layer on its one surface 5A, a release sheet may be attached to the one surface 5A. The release sheet is preferably peeled off from one side 5A during use.
また、カバー部材５は、図７に示すように、タッカー、ビスなどのカバー部材５とは別部材である留付材６Ａによって仕切り部１１の外面１１Ａに固定され、カバー部材５の外周側から巻かれた紐状部材及び粘着テープ等の留付材６Ｂによって挿通体２１に固定する態様とすることができる。もちろん、これらの２以上の組み合わせにより、カバー部材５は、仕切り部１１及び挿通体２１に固定されてもよい。 Further, as shown in FIG. 7, the cover member 5 is fixed to the outer surface 11A of the partition portion 11 by a fastening material 6A, which is a separate member from the cover member 5, such as a tacker or a screw, and is fixed from the outer circumferential side of the cover member 5. It can be fixed to the insertion body 21 using a wound string-like member and a fastening material 6B such as adhesive tape. Of course, the cover member 5 may be fixed to the partition part 11 and the insertion body 21 by a combination of two or more of these.
カバー部材５は、仕切り部１１及び挿通体２１に固定されて設置され、テープ状部材４とカバー部材５との間に空隙４０を形成するように設置する。テープ状部材４とカバー部材５との間に空隙４０があることで、カバー部材５は、挿通体２１の軸方向の動きに対する裕度を持って固定される。カバー部材５が裕度を持って挿通体２１に固定されることで、カバー部材５の設置後に、カバー部材５の内側に配置された挿通体２１を軸方向に動かした場合であっても、カバー部材５の裕度によってカバー部材５が挿通体２１と一緒に動いてしまうことを緩衝する。カバー部材５が挿通体２１と一緒に動いてしまうことを緩衝することで、カバー部材５が区画貫通部１５からずれることを抑制することができる。つまり、このような構成とすることで、カバー部材５を区画貫通部１５における適切な位置に維持して配置し続けることができ、区画貫通部１５の耐火性を維持することができる。
テープ状部材４とカバー部材５との間に空隙４０があり、カバー部材５が挿通体２１の軸方向の動きに対して裕度を持って固定される構成としては種々の形態を取り得る。例えば、カバー部材５の少なくとも一部が屈曲ないし湾曲できるような柔軟性や伸縮性を有する材料による構成、及び、カバー部材５の少なくとも一部が挿通体２１に対してたるみを有するように固定する構成等が挙げられる。
The cover member 5 is fixedly installed on the partition portion 11 and the insertion body 21, and is installed so as to form a gap 40 between the tape-like member 4 and the cover member 5. Since there is a gap 40 between the tape-like member 4 and the cover member 5, the cover member 5 is fixed with a margin against the movement of the insertion body 21 in the axial direction. By fixing the cover member 5 to the insertion body 21 with a margin, even if the insertion body 21 arranged inside the cover member 5 is moved in the axial direction after the installation of the cover member 5, The tolerance of the cover member 5 buffers the cover member 5 from moving together with the insertion body 21. By buffering the cover member 5 from moving together with the insertion body 21, it is possible to suppress the cover member 5 from shifting from the compartment penetration part 15. That is, with such a configuration, the cover member 5 can be maintained and disposed at an appropriate position in the compartment penetration part 15, and the fire resistance of the division penetration part 15 can be maintained.
There is a gap 40 between the tape-like member 4 and the cover member 5, and various forms can be taken as a structure in which the cover member 5 is fixed with a margin against the movement of the insertion body 21 in the axial direction. For example, at least a portion of the cover member 5 is made of a flexible or stretchable material that can be bent or curved, and at least a portion of the cover member 5 is fixed so as to have slack with respect to the insertion body 21. Examples include configuration.
カバー部材５によって、仕切り部１１及び挿通体２１との間に空隙４０を形成されたことで、空隙４０は、テープ状部材４及びカバー部材５との間の空気層として機能する。空隙４０がテープ状部材４及びカバー部材５との間の空気層として機能することで、区画貫通処理構造における耐火性能を向上させることができる。 Since the gap 40 is formed between the partition part 11 and the insertion body 21 by the cover member 5, the gap 40 functions as an air layer between the tape-like member 4 and the cover member 5. Since the void 40 functions as an air layer between the tape-like member 4 and the cover member 5, it is possible to improve the fire resistance performance of the compartment penetration treatment structure.
以上の本実施形態の構成によれば、区画貫通部１５の開口１３Ｃ内部の間隙１３Ｅが、テープ状部材４及びカバー部材５により塞がれ、かつこれらうち少なくとも、テープ状部材４が、耐火材を有する。したがって、区画貫通部処理構造１０に適切な耐火性能を付与できる。
テープ状部材４の構成は上記の通りであるが、本実施形態において、テープ状部材４の耐火材層、特に膨張材により形成される耐火材層を外周側の最外層に設けることが好ましい。テープ状部材４が膨張材により形成される耐火材層を外周側の最外層に設けることで、火災等により耐火材層が熱膨張した場合に、カバー部材５により保持され、膨張残渣の欠落などを防止できる。
本実施形態の構成のように、カバー部材５がある場合には、テープ部材４によって、間隙１３Ｅの全てを塞ぐ必要はなく、間隙１３Ｅの一部をカバー部材４により塞ぎ、そして間隙１３Ｅの残部をテープ部材５により塞ぐ形態とすることができる。
また、上記で説明した通り、区画貫通処理構造１０は、テープ状部材４とカバー部材５とを用意し、まず、テープ状部材４を挿通体２１に一周以上巻き付けて配置し、仕切り部１１に設けられる区画貫通部１５の開口１３Ｃ及び仕切り部１１の外面１１Ｂと挿通体２１との間の間隙１３Ｅの少なくとも一部を塞ぐようにテープ状部材４を設置する。次いで、テープ状部材４を覆うようにカバー部材５を仕切り部１１及び挿通体２１に固定することで施工できる。したがって、その施工が容易である。
また、本実施形態では、耐火パテ、ロックウールなどの充填材を区画貫通部１５の内部に配置することなく、テープ状部材４及びカバー部材５により耐火構造が形成されるので、作業者によるバラつきが生じることもない。
According to the configuration of this embodiment described above, the gap 13E inside the opening 13C of the partition penetrating portion 15 is closed by the tape-shaped member 4 and the cover member 5, and at least the tape-shaped member 4 is made of fireproof material. has. Therefore, appropriate fire resistance can be imparted to the compartment penetration treatment structure 10.
The configuration of the tape-shaped member 4 is as described above, but in this embodiment, it is preferable that the refractory material layer of the tape-shaped member 4, particularly the refractory material layer formed of an expandable material, be provided as the outermost layer on the outer peripheral side. Since the tape-like member 4 is provided with a fireproof material layer made of an expanding material as the outermost layer on the outer circumferential side, when the fireproof material layer is thermally expanded due to a fire, etc., it is retained by the cover member 5, and expansion residues are prevented from being lost. can be prevented.
As in the configuration of this embodiment, when the cover member 5 is provided, it is not necessary to close all of the gap 13E with the tape member 4, but a part of the gap 13E is closed with the cover member 4, and the remainder of the gap 13E is closed with the tape member 4. can be closed with a tape member 5.
Further, as explained above, in the compartment penetration treatment structure 10, the tape-like member 4 and the cover member 5 are prepared, and the tape-like member 4 is first wound around the insertion body 21 for one or more times and arranged, and then The tape-like member 4 is installed so as to close at least a portion of the opening 13C of the compartment penetration portion 15 provided and the gap 13E between the outer surface 11B of the partition portion 11 and the insertion body 21. Next, the cover member 5 is fixed to the partition portion 11 and the insertion body 21 so as to cover the tape-like member 4, thereby performing the construction. Therefore, its construction is easy.
In addition, in this embodiment, the fireproof structure is formed by the tape-like member 4 and the cover member 5 without disposing a filler such as fireproof putty or rock wool inside the compartment penetration part 15, so that variations due to operator will not occur.
さらに、本実施形態では、少なくともカバー部材５が露出しており、外部から視認可能である。また、カバー部材５を固定するための固定部材が設けられる場合、固定部材も外部から視認可能な位置に配置するとよい。そして、区画貫通部１５の内部には、挿通体２１以外の部材が何も設けられない。そのため、区画貫通処理材は、規定通り施工されたことが目視や写真撮影により簡単に点検できる。また、施工忘れなども発生にくくなる。 Furthermore, in this embodiment, at least the cover member 5 is exposed and is visible from the outside. Moreover, when a fixing member for fixing the cover member 5 is provided, the fixing member is also preferably arranged at a position that is visible from the outside. Further, no member other than the insertion body 21 is provided inside the partition penetrating portion 15. Therefore, it is possible to easily check whether the compartment penetration treatment material has been constructed according to regulations by visual inspection or by taking photographs. In addition, forgetting to perform construction is less likely to occur.
［第２の実施形態の変形例］
図７で示した区画貫通処理構造１０では、カバー部材５は、一方が挿通体２１に固定して設置する態様を示したが、図８に示すように、挿通体２１に巻きつけられて配置されたテープ状部材４に固定して設置する態様でもよい。
このような態様とすることで、少なくともテープ状部材４の端面４Ｂが露出しており、外部から視認可能である。そのため、区画貫通処理材は、規定通り施工されたことが目視や写真撮影により簡単に点検できる。また、施工忘れなども発生にくくなる。
[Modification of second embodiment]
In the compartment penetration treatment structure 10 shown in FIG. 7, the cover member 5 is installed with one side fixed to the insertion body 21, but as shown in FIG. It may also be a mode in which it is fixedly installed on the tape-like member 4 that has been attached.
With this configuration, at least the end surface 4B of the tape-like member 4 is exposed and can be visually recognized from the outside. Therefore, it is possible to easily check whether the compartment penetration treatment material has been constructed according to regulations by visual inspection or by taking photographs. In addition, forgetting to perform construction is less likely to occur.

The thickness of the sound absorbing layer is not particularly limited, but is, for example, 0.1 to 10 mm, preferably 0.5 to 5 mm. When the sound absorbing layer has a thickness that is equal to or less than these upper limit values, installation of the tape-shaped member 4 can be facilitated. Furthermore, when the sound absorption layer has a thickness equal to or greater than these lower limits, it becomes easier to ensure sound absorption performance.

Further, the sound insulation layer can also be made of a resin material highly filled with an inorganic filler such as calcium carbonate. Specifically, it is preferably composed of a resin composition containing 300 to 600 parts by mass of an inorganic filler, and preferably composed of a resin composition containing 350 to 550 parts by mass of an inorganic filler based on 100 parts by mass of olefin resin. More preferably, the resin composition contains 400 to 500 parts by mass. In this way, the resin material highly filled with inorganic filler has a large mass per unit volume, thereby effectively exhibiting a sound insulation effect.
The thickness of the sound insulating layer is not particularly limited, but is, for example, 0.1 to 10 mm, preferably 0.5 to 5 mm. When the sound insulating layer has a thickness that is equal to or less than these upper limit values, installation of the tape-shaped member 4 can be facilitated. Furthermore, when the sound insulation layer has a thickness equal to or greater than these lower limits, it becomes easier to ensure sound insulation performance.
